Question
Take a graph paper and mark the points P(2, 1), Q(7, 1) and R(7,5). Taking QR as the line of symmetry, obtain and write the co-ordinates of point S.
Solution
Steps of construction :
(i) Plot the points P, Q and Ras per given data.
(ii) Point S symmetrical about QR is a point with vertices x= 12 and y = 1 i.e. 5 unit right of line RQ.
(iii) Plot S( 12, 1)
(iv) Join PR, PS and RS
